| dc.description.abstract | Orthorombic perovskite SrRuO3 and SrSnO3 have been studied for their unique properties. There is also theoretical expectation that Sr(Ru1-xSnx)O3 can be made a half-metal or dilute magnetic semiconductor by varing the doping ratio x. In order to study the doping effect, Sr(Ru1-xSnx)O3 were synthesized with a solid state reaction method and physical properties were measured. The volume of Sr(Ru,Sn)O3 change follows the Vegards law. In the Ru-rich side, the ferromagnetic transition temperature of SrRuO3 decreases with Sn doping, accmompanied by a change in resistivity. On the other hand, Sn-rich SrRu1-xSnxO3 samples show magnetic hysteresis in their magnetization. While SrRu0.3Sn0.7O3 has a positive Curie temperature and the coercive field increases with cooling, SrRu0.1Sn0.9O3 has a negative Curie temperature and the coercive field decreases with cooling. | - |
